Past location-based communication with mobile devices

ABSTRACT

For location-based communication with mobile devices, a condition is received, at a device associated with a caller, where the condition has to be satisfied by a callee at a past location, the past location being a place where different callees with different mobile devices are present at different times. At the device associated with the caller, an instruction is received for making a telecommunication call to a mobile device of a potential callee in a set of potential callees, where each mobile device associated with each potential callee in set of potential callees was present at the past location at a past time, and where each potential callee in the set of potential callees satisfies the condition at the past location. Using a processor and a memory in the device associated with the caller, the telecommunication call is initiated to mobile devices associated with a subset of potential callees.

TECHNICAL FIELD

The present invention relates generally to a method, system, and computer program product for telecommunications with mobile devices. More particularly, the present invention relates to a method, system, and computer program product for past location-based communication with mobile devices.

BACKGROUND

Mobile devices proliferate all aspects of daily life and are usable for telecommunications. Users with mobile devices frequently travel to a variety of places for a variety of purposes. It is conceivable that regardless of what or where a place might be, if there is a human user in that place, it is very likely that the user has a mobile device on the user's person or otherwise available to the user with which to establish a telecommunications call (hereinafter, “call”).

A call is any suitable method of telecommunication, including but not limited to audio telephonic communications, video telecommunications, textual messaging, taptically or haptically telecommunicating information, and generally telecommunication of data in these and other forms. Any type of mobile device can be used for a call. A mobile device is capable of relocating from one location to another as the user associated with the mobile device moves from one location to another. As some non-limiting examples, the mobile device can take the form of a cellular phone, a smartphone device, a tablet computer, a portable computing platform, a wearable device, and the like.

A typical call begins with a calling user (hereinafter, “caller”) dialing a number associated with a mobile device that is associated with a called user (hereinafter, “callee”). A service provider connects the call between the caller's telecommunication device and the callee's mobile device using one or more service provider systems. In some cases, the caller selects a callee's name, such as from a phonebook or a similar contacts management application, and the caller's device calls the number stored relative to the callee's name in the phonebook.

In some cases, a caller may not know the callee or a callee's number. A caller can use a directory service, whereby the caller identifies the intended callee by name, address, or both, and the directory service provides the callee's number to the caller, connects the call between the caller and the callee, or both.

The illustrative embodiments recognize that for the directory service to work using only the address, the callee's number has to be permanently associated with that address, even if the number is assigned to a mobile device. In other words, if a callee has to be reached only by knowing the callee's address, the callee's number must be unchangeably associated with the address, even if the device associated with the number is mobile.

The illustrative embodiments recognize that presently, there is no available method by which a caller could call any callee who may be present at a given location at a given time. In other words, if a caller were interested in calling anyone who may be present at or around a specified geographical location, during a given period, the caller will be able to call that location only if either a number is permanently associated with that location and the caller calls that number, or the caller calls a specific known callee whose presence at the location is a known fact to the caller.

The illustrative embodiments recognize that such a deficiency in the present telecommunications systems is severely limiting in many circumstances. The illustrative embodiments recognize that under certain circumstances, a caller may want to call any callee who satisfies a past time-related criterion. A past-time related criterion is also interchangeably referred to as a past-related criterion, past criterion, or simply “criterion” or a grammatical variation thereof, unless expressly distinguished where used.

A location visited by a caller or a potential callee during a past period is referred to hereinafter as a “past location”. A past-related criterion is a criterion or condition, which may specify a past location, or from which a past location can be deduced, and which has a condition that was either satisfied during a past period or is satisfied at the time of the call by the caller or a potential callee.

Generally, a past-related criterion takes the following two part form—(i) a past location of the caller or a callee, and (ii) a condition satisfied in the past or the present. Some examples of part (ii) include, but are not limited to—a callee who was co-located with the caller (at the past location of part (i) at a past time); a callee who was co-located with someone other than the caller (at the past location of part (i) at a past time); a callee who was at an event (at the past location of part (i) at a past time); a callee who was co-located with someone other than the caller during an event (at the past location of part (i) at a past time). Some more examples of part (ii) include, but are not limited to—a callee who was (at the past location of part (i) at a past time) and satisfies a condition at the time of the call; a callee who was (at the past location of part (i) at a past time) and is co-located with the caller at the time of the call; a callee who was (at the past location of part (i) at a past time) and is co-located with someone other than the caller at the time of the call; a callee who was (at the past location of part (i) at a past time) and who is doing or not doing something at the time of the call; and a callee who was (at the past location of part (i) at a past time) and is co-located with an event at the time of the call.

Some example use-cases of a past-related criterion are provided now. For example, a caller might want to call anyone—even an unknown callee—who may be at a location where the caller visited earlier, to ask whether they see the caller's lost wallet there. The past location is of the caller, the condition is a present presence of the callee at the past location of the caller, and different callees may be present at that location at different times.

As another example, a caller may be a law enforcement agency who might want to call anyone—even an unknown callee—who was at an establishment at a past time, to ask whether the callee saw a wanted person engaged in an unlawful activity then and there. The wanted person is someone other than the caller, the establishment visited in the past by the callee is the past location of part (i), and the callee's co-location with the wanted person at the past time at the establishment is the condition of part (ii). Different callees, with different mobile devices, and with different numbers or identifiers, may be present at the establishment at different times.

As another example, a caller might want to call anyone—even an unknown callee—who was present at a particular restaurant when the caller had lunch there yesterday. The restaurant is the location, the past time is yesterday at the time the caller had lunch, and the condition is that the callee and caller were co-located then and there. As in the other examples above, different callees, with different mobile devices, and with different numbers or identifiers, may be present at the callee's location at different times.

As another example, the caller might be interested in calling someone who is presently at a location where the caller conducted business, or spent the most time, or performed an action, or experienced an event, etc., at a past time or during a past period. The location where the caller did something at the past time is the past location, the callee's present presence there is the condition. Again, different callees, with different mobile devices, and with different numbers or identifiers, may be present at that location at different times.

Furthermore, the caller might be interested in calling one or more than one callee who may be located at a past location and satisfies a caller-specified condition according to a past-related criterion. Furthermore, the caller may want at least n callees to respond, no more than n callees to respond, n or more callees to respond, or some combination thereof. Furthermore, the caller may want one or more responses within a given period. Not only could different callees, with different mobile devices, and with different numbers or identifiers, be present at the location during the period, but also the group of potential callees may change during the period.

Furthermore, the past location may be determined or determinable, in any suitable manner, at or after the past time. For example, the past location can be determined by determining a Global Positioning System (GPS) coordinates, cell tower triangulation, an application on a mobile device reporting a position in relation to an access point or beacon, an access point or beacon reporting the mobile device's proximity with them, and other similarly purposed known techniques.

Additionally, the past location of part (i) of the past-related criterion is not limited to a singular location, and can be one or more locations. Similarly, not just one but any number of conditions can be specified as part (ii) of a past-related criterion.

These examples of past-related criteria are not intended to be limiting. From this disclosure, those of ordinary skill in the art will be able to conceive many other conditions and use-cases to form other past-related criteria in a similar manner and the same are contemplated within the scope of the illustrative embodiments.

The illustrative embodiments recognize that presently available methods of calling are severely limited in establishing a call in these and other similar circumstances. Thus, a solution for calling one or more transient callees or callee-associated mobile devices based on a mobile device's location and a condition being satisfied is needed and will be beneficial.

DETAILED DESCRIPTION

The illustrative embodiments used to describe the invention generally address and solve the above-described problems and other problems related to calling one or more transient and unknown callees based on a past location of a caller or the callee at a past time, subject to a condition that is satisfied at the past time or at the time of the call. The illustrative embodiments provide a method, system, and computer program product for past location-based communication with mobile devices.

Within the scope of the illustrative embodiments, a location call is a call placed by one caller to one or more transient and unknown callees based on the callees' location. From the caller's perspective, the location call is an outbound location call. From a callee's perspective, the location call is an inbound location call.

Within the scope of the illustrative embodiments, a location includes a precisely specified geographical point, a description of a structure or landmark located in a geographical region, a defined and bound geographical area, a geographical point or area that meets a criterion or condition, or some combination thereof.

An embodiment can be implemented as an application to execute on a mobile device. One embodiment enables a caller to place an outbound location call. Another embodiment enables a callee to respond to, accept, or otherwise handle an incoming location call. Another embodiment is configured to facilitate features described with respect to both—outbound location calls and inbound location calls.

An embodiment detects that the caller wishes to initiate a location call. For example, a caller selecting an area or a location on a map application triggers the detection that the caller wishes to initiate a location call. For example, the caller may point to, or draw on a map presentation to select an area or a location. A profile configuration of the caller or another selection tool allows the caller to specify the size of the area, such as by selecting a default or specified radius from the pointed-to location. For example, when the caller points to a location on a map, a pre-configured preference selects an area of n feet radius centered at the selected location. As another example, when the user selects an office building, the entire office campus, or a pre-defined area therein, may be selected.

According to another embodiment, a caller inputting a description of an area or a location, such as via a natural language interface, triggers the detection that the caller wishes to initiate a location call. For example, a caller can speak a description into an audio input interface, type a question in a natural language, such as, for example, “who is at the park where I lost my wallet?” or “call someone who was at the Smith party yesterday,” or “Find anyone who saw John Doe get into an accident at the intersection of First street and Avenue K.”

According to another embodiment, a caller selecting or highlighting a description of an area or a location, such as on a calendar application, triggers the detection that the caller wishes to initiate a location call. For example, if the caller selects a past meeting on the caller's calendar, a location of the past meeting is automatically selected.

A profile configuration of the caller or another selection tool allows the caller to specify when such an input is to be construed as specifying a past location for a past-related criterion, a condition for a past-related criterion, or both. For example, the caller may configure in the profile that when the caller provides an input with a temporal aspect in specific one or more applications, the input should be construed as a past-related criterion for a location call.

According to another embodiment, a caller expressly inputting a description of a past-related criterion, such as via a natural language interface, triggers the detection that the caller wishes to initiate a location call based on the past-related criterion. For example, a caller can speak a description into an audio input interface, or type a question in a natural language, such as, for example, “who was with John when he had a heart-attack?” Notice that a past location is not specified but is implied in this example. There was a location where John experienced the symptoms of a heart-attack. An embodiment derives or deduces that past location from other data, such as from analyzing an email message or a voicemail to the caller from one of John's family members. Then, the condition of part (ii) becomes a co-location of a callee with John at that location at that time in the past.

These examples of determining the past location and the condition from a caller's actions are not intended to be limiting. From this disclosure, those of ordinary skill in the art will be able to conceive many other ways of determining the past location and the condition from these and other actions of a caller and the same are contemplated within the scope of the illustrative embodiments.

An embodiment further presents the caller a user interface from where the caller can configure a number of criteria or conditions for the outbound location call, such as part (i) of a past-related criteria or information sufficient to deduce part (i), part (ii) of a past-related criteria or information sufficient to deduce part (ii), or some combination thereof. For example, according to one embodiment, the caller can specify when the potential callees should be present, what defines the past location, and which condition should be satisfied at which time to the location call. As another example, according to another embodiment, the caller can specify how many potential callees should be present at the past location. According to another embodiment, the caller can specify how many potential callees should respond to the location call. According to another embodiment, the caller can specify a timeout period within which a potential callee should respond; otherwise the location call should be terminated. According to another embodiment, the caller can specify the request the caller has for a callee who answers the location call, e.g., a text message that should be presented to the callee who accepts the location call.

Whether a condition of the past-related criterion has been satisfied can be determined by the service provider. For example, a server application maintains historical records of the traversals of the devices of the caller and potential callees. Given a condition, the server application can select those devices, and the callees associated therewith, who satisfy the condition in the past-related criterion. Accordingly, an embodiment transmits the location information if available, a present or past condition from which to determine the location, a condition in the past-related criterion that should be satisfied, or some combination thereof, to a service provider whose network will be utilized for the location call.

A server application on the service provider's network receives the past location or information to deduce the past location, a condition of the past-related criterion the criterion, or some combination thereof. The server application identifies a set of one or more mobile devices that were situated at the specified location at the specified time. The server application selects from the set, those device as the potential callees which satisfy the time, location, and condition of the past-related criterion.

The server application prepares a callee list. The callee list includes the selected mobile devices and their associated identifiers or numbers. Each callee associated with an identified mobile device is a potential callee who satisfies the time, place, and condition of the past-related criterion.

In one embodiment, the server application provides the callee list to the application executing on the caller's device. In such an embodiment, an identity of a potential callee, an identifier or number of a potential callee's mobile device, a normalized form of the identity or identifier, or some combination thereof, are revealed to the caller. Even though the potential callees are unknown to the caller, the caller is able to select one or more potential callees, reject one or more callees, or both, based on some caller-determined criteria.

As one example, assume that several callees are listed as potential callees on the list sent to the caller. Different potential callees may satisfy the past-related criterion differently, such as to different degrees, at different times, at different distances from a location, or some combination thereof. One non-limiting example caller-determined criterion for selecting a potential callee from the list can be a degree to which that callee satisfies part (ii) of the past-related criterion.

Note that the selection of some potential callees from a callee list need not be an overt action on the part of the caller. In one embodiment, configuration information used by the embodiment can automatically select or reject a potential callee from a callee list when the callee list is available from the service provider.

In another embodiment, the server application does not provide the callee list to the application executing on the caller's device, but selects one or more callees at the server application. The selection process on the server application can be similar to the selection process on the caller's device, as described above. In such an embodiment, an identity of a potential callee, an identifier or number of a potential callee's mobile device, or some combination thereof, are not revealed to the caller. The caller is not able to select or reject one or more potential callees, but the server application does the selection or rejection on the caller's behalf.

One or more callees, who satisfy the time, location, and condition of a past-related criterion, are selected in one of the manners described herein. An embodiment creates an instruction to initiate the location call. For example, one embodiment passes, as instructions to the server application, the selected callees, if a selection was made by the caller from the callee list. As another example, another embodiment passes, as instructions to the server application, any data, such as a text message, that the caller has configured to provide to a callee who accepts the location call.

Either to a caller-selected list of potential callees when the caller selects some potential callees, or to all potential callees in the callee list created by the server application, the server application initiates the location call using the instructions. Optionally, if an embodiment has provided any data to be transmitted to a callee, the server application passes such data to each callee mobile device with which the location call is initiated.

An embodiment allows inbound location call configuration for a callee. A user who could be a potential callee for a past location call can configure the embodiment with one or more preferences for the handling of such past location call. For example, a user can configure the embodiment with a black zone. A black zone is a location or area where the user does not want to participate in one or more location calls.

The user can further configure specific properties of the location calls in which the user does not want to participate while the user's mobile device is located in the black zone. A user can also configure a time period when the user does not participate in location calls while in the black zone. A user can also configure a time period, i.e., a Do Not Disturb (DND) period, when the user does not participate in location calls regardless of where the user is located. A user can also configure a whitelist (or a blacklist) of potential caller's, from any of whom a location call is acceptable (not acceptable).

An embodiment enables a potential callee to configure a combination of these and other similar configuration parameters. These examples of callee configurations are not intended to be limiting. From this disclosure, those of ordinary skill in the art will be able to conceive many other configuration parameters that can be configured in a similar manner, and the same are contemplated within the scope of the illustrative embodiments.

An embodiment further manages the mobile device associated with a potential callee, such as to manage the callee's privacy-related preferences. For example, a callee might want to not participate in a location call not only by rejecting a location call but also by configuring the mobile device in such a way that the mobile device will not be included in a callee list for a specified location. For example, one embodiment hides or otherwise prevents the mobile device's location to become known to the server application. Thus, when the server application does not have the location information of a mobile device, the server application cannot include the mobile device in a callee list. As another example, another embodiment masquerades the mobile device's location, such as by manipulating the device's location such that the device appears to be at a location other than the device's actual location.

An embodiment can manage the mobile device on which the embodiment is implemented such that the mobile device's behavior can be modified in a variety of ways. For example, an embodiment can modify the mobile device's behavior differently for different incoming location calls, based on a present location of the device when an location call is received, based on time when an location call is received, based on a source or caller of a location call (when the caller is identified to the callee), or some combination of these and other factors.

An embodiment further transmits one or more callee preferences described herein to a service provider. Such a transmission allows or prevents a server application from including the user's mobile device in a list of potential callees.

When an inbound location call is received at the mobile device, an embodiment allows a variety of call handling options to the callee. For example, the embodiment allows the callee to accept or answer the call, decline or reject the call, allows the call to fail, or manipulate a configuration parameter of the device such that the device no longer complies with a requirement of the location call.

If the callee accepts a location call, an embodiment further responds to the caller with any data that may be requested from the callee. For example, the embodiment can capture and transmit an image of a surrounding where the mobile device is present. As another example, an embodiment can transmit a message or a disclaimer to the caller before the callee and the caller communicate in the call. An embodiment can make these and other similarly purposed data transmissions at the beginning of the location call, during the location call, prior to a termination of the location call, or even after a location call has terminated.

For example, using an embodiment, a caller may wish to perform a poll. The caller may leave the poll open for five minutes after which the poll closes and the location call ends. The embodiment then summarizes the results of the poll and transmits to some or all callees. For example, the result data may be transmitted to only those callees who participated in the poll, or to all potential callees in the group. Such a transmission of the result data would be a transmission done after the location call terminates. Those of ordinary skill in the art will be able to conceive may other circumstances of data transmissions that occur at the beginning of the location call, during the location call, prior to a termination of the location call, or even after a location call has terminated, and the same are contemplated within the scope of the illustrative embodiments.

A method of an embodiment described herein, when implemented to execute on a device or data processing system, comprises substantial advancement of the functionality of that device or data processing system in calling a mobile device based on the device's past location and the satisfaction of a past-related criterion. For example, prior-art requires that a caller be able to identify a callee either by an identity of the callee or by a fixed association of a telecommunication identifier, e.g., a phone number, with a location. An embodiment enables a caller to make a location call without knowing the identity of a callee at a location, without the location being associated with any particular telecommunication identifier, or both. Furthermore, an embodiment enables a caller to specify a past location and a condition that a callee has to satisfy at a given time to be eligible as a callee. Operating in a manner described herein, an embodiment performs past location-based communication with mobile devices. Such manner of operating a telecommunication system is unavailable in presently available devices or data processing systems. Thus, a substantial advancement of such devices or data processing systems by executing a method of an embodiment facilitates past condition based calls to a transient and dynamic set of callees based on a location of the set of callees.

FIGS. 1 and 2 are only examples and are not intended to assert or imply any limitation with regard to the environments in which different embodiments may be implemented. A particular implementation may make many modifications to the depicted environments based on the following description.

FIG. 1 depicts a block diagram of a network of data processing systems in which illustrative embodiments may be implemented. Data processing environment 100 is a network of computers in which the illustrative embodiments may be implemented. Data processing environment 100 includes network 102. Network 102 is the medium used to provide communications links between various devices and computers connected together within data processing environment 100. Network 102 may include connections, such as wired communication links, wireless communication links, or fiber optic cables.

Clients or servers are only example roles of certain data processing systems connected to network 102 and are not intended to exclude other configurations or roles for these data processing systems. Server 104 and server 106 couple to network 102 along with storage unit 108. Software applications may execute on any computer in data processing environment 100. Clients 110, 112, and 114 are also coupled to network 102. A data processing system, such as server 104 or 106, or client 110, 112, or 114 may contain data and may have software applications or software tools executing thereon.

Only as an example, and without implying any limitation to such architecture, FIG. 1 depicts certain components that are usable in an example implementation of an embodiment. For example, servers 104 and 106, and clients 110, 112, 114, are depicted as servers and clients only as example and not to imply a limitation to a client-server architecture. As another example, an embodiment can be distributed across several data processing systems and a data network as shown, whereas another embodiment can be implemented on a single data processing system within the scope of the illustrative embodiments. Data processing systems 104, 106, 110, 112, and 114 also represent example nodes in a cluster, partitions, and other configurations suitable for implementing an embodiment.

Device 132 is an example of a device described herein. For example, device 132 can take the form of a smartphone, a tablet computer, a laptop computer, client 110 in a stationary or a portable form, a wearable computing device, or any other suitable device. Any software application described as executing in another data processing system in FIG. 1 can be configured to execute in device 132 in a similar manner. Any data or information stored or produced in another data processing system in FIG. 1 can be configured to be stored or produced in device 132 in a similar manner.

Device 132 is a mobile device according to an embodiment, e.g., a tablet computer. Device 142 is another example of a mobile device, such as a smartphone. Client 112 is an example of a telecommunication device, including but not limited to a mobile device. Client applications 113, 134, and 144 each implements an embodiment described herein. As a non-limiting example, client application 134 may implement certain callee oriented features of one or more embodiments described herein. As another non-limiting example, client application 144 may implement certain caller oriented features and certain callee oriented features of one or more embodiments described herein. As another non-limiting example, client application 113 may implement certain caller oriented features of one or more embodiments described herein. Generally, a client application can implement any combination of caller oriented features and callee oriented features without limitation. Server application 105 is an application that executes on the server-side of a service provider's network in a manner described herein.

Servers 104 and 106, storage unit 108, and clients 110, 112, and 114 may couple to network 102 using wired connections, wireless communication protocols, or other suitable data connectivity. Clients 110, 112, and 114 may be, for example, personal computers or network computers.

In the depicted example, server 104 may provide data, such as boot files, operating system images, and applications to clients 110, 112, and 114. Clients 110, 112, and 114 may be clients to server 104 in this example. Clients 110, 112, 114, or some combination thereof, may include their own data, boot files, operating system images, and applications. Data processing environment 100 may include additional servers, clients, and other devices that are not shown.

In the depicted example, data processing environment 100 may be the Internet. Network 102 may represent a collection of networks and gateways that use the Transmission Control Protocol/Internet Protocol (TCP/IP) and other protocols to communicate with one another. At the heart of the Internet is a backbone of data communication links between major nodes or host computers, including thousands of commercial, governmental, educational, and other computer systems that route data and messages. Of course, data processing environment 100 also may be implemented as a number of different types of networks, such as for example, an intranet, a local area network (LAN), or a wide area network (WAN). FIG. 1 is intended as an example, and not as an architectural limitation for the different illustrative embodiments.

Among other uses, data processing environment 100 may be used for implementing a client-server environment in which the illustrative embodiments may be implemented. A client-server environment enables software applications and data to be distributed across a network such that an application functions by using the interactivity between a client data processing system and a server data processing system. Data processing environment 100 may also employ a service oriented architecture where interoperable software components distributed across a network may be packaged together as coherent business applications.

With reference to FIG. 2, this figure depicts a block diagram of a data processing system in which illustrative embodiments may be implemented. Data processing system 200 is an example of a computer, such as servers 104 and 106, or clients 110, 112, and 114 in FIG. 1, or another type of device in which computer usable program code or instructions implementing the processes may be located for the illustrative embodiments.

Data processing system 200 is also representative of a data processing system or a configuration therein, such as data processing system 132 and 142 in FIG. 1 in which computer usable program code or instructions implementing the processes of the illustrative embodiments may be located. Data processing system 200 is described as a computer only as an example, without being limited thereto. Implementations in the form of other devices, such as device 132 and 142 in FIG. 1, may modify data processing system 200, such as by adding a touch interface, and even eliminate certain depicted components from data processing system 200 without departing from the general description of the operations and functions of data processing system 200 described herein.

In the depicted example, data processing system 200 employs a hub architecture including North Bridge and memory controller hub (NB/MCH) 202 and South Bridge and input/output (I/O) controller hub (SB/ICH) 204. Processing unit 206, main memory 208, and graphics processor 210 are coupled to North Bridge and memory controller hub (NB/MCH) 202. Processing unit 206 may contain one or more processors and may be implemented using one or more heterogeneous processor systems. Processing unit 206 may be a multi-core processor. Graphics processor 210 may be coupled to NB/MCH 202 through an accelerated graphics port (AGP) in certain implementations.

In the depicted example, local area network (LAN) adapter 212 is coupled to South Bridge and I/O controller hub (SB/ICH) 204. Audio adapter 216, keyboard and mouse adapter 220, modem 222, read only memory (ROM) 224, universal serial bus (USB) and other ports 232, and PCI/PCIe devices 234 are coupled to South Bridge and I/O controller hub 204 through bus 238. Hard disk drive (HDD) or solid-state drive (SSD) 226 and CD-ROM 230 are coupled to South Bridge and I/O controller hub 204 through bus 240. PCI/PCIe devices 234 may include, for example, Ethernet adapters, add-in cards, and PC cards for notebook computers. PCI uses a card bus controller, while PCIe does not. ROM 224 may be, for example, a flash binary input/output system (BIOS). Hard disk drive 226 and CD-ROM 230 may use, for example, an integrated drive electronics (IDE), serial advanced technology attachment (SATA) interface, or variants such as external-SATA (eSATA) and micro-SATA (mSATA). A super I/O (SIO) device 236 may be coupled to South Bridge and I/O controller hub (SB/ICH) 204 through bus 238.

Memories, such as main memory 208, ROM 224, or flash memory (not shown), are some examples of computer usable storage devices. Hard disk drive or solid state drive 226, CD-ROM 230, and other similarly usable devices are some examples of computer usable storage devices including a computer usable storage medium.

An operating system runs on processing unit 206. The operating system coordinates and provides control of various components within data processing system 200 in FIG. 2. The operating system may be a commercially available operating system such as AIX® (AIX is a trademark of International Business Machines Corporation in the United States and other countries), Microsoft® Windows® (Microsoft and Windows are trademarks of Microsoft Corporation in the United States and other countries), Linux® (Linux is a trademark of Linus Torvalds in the United States and other countries), iOS™ (iOS is a trademark of Cisco Systems, Inc. licensed to Apple Inc. in the United States and in other countries), or Android™ (Android is a trademark of Google Inc., in the United States and in other countries). An object oriented programming system, such as the Java™ programming system, may run in conjunction with the operating system and provide calls to the operating system from Java™ programs or applications executing on data processing system 200 (Java and all Java-based trademarks and logos are trademarks or registered trademarks of Oracle Corporation and/or its affiliates).

Instructions for the operating system, the object-oriented programming system, and applications or programs, such as server application 105 in FIG. 1 and client applications 113, 134, and 144 in FIG. 1, are located on storage devices, such as hard disk drive 226, and may be loaded into at least one of one or more memories, such as main memory 208, for execution by processing unit 206. The processes of the illustrative embodiments may be performed by processing unit 206 using computer implemented instructions, which may be located in a memory, such as, for example, main memory 208, read only memory 224, or in one or more peripheral devices.

The hardware in FIGS. 1-2 may vary depending on the implementation. Other internal hardware or peripheral devices, such as flash memory, equivalent non-volatile memory, or optical disk drives and the like, may be used in addition to or in place of the hardware depicted in FIGS. 1-2. In addition, the processes of the illustrative embodiments may be applied to a multiprocessor data processing system.

In some illustrative examples, data processing system 200 may be a personal digital assistant (PDA), which is generally configured with flash memory to provide non-volatile memory for storing operating system files and/or user-generated data. A bus system may comprise one or more buses, such as a system bus, an I/O bus, and a PCI bus. Of course, the bus system may be implemented using any type of communications fabric or architecture that provides for a transfer of data between different components or devices attached to the fabric or architecture.

A communications unit may include one or more devices used to transmit and receive data, such as a modem or a network adapter. A memory may be, for example, main memory 208 or a cache, such as the cache found in North Bridge and memory controller hub 202. A processing unit may include one or more processors or CPUs.

The depicted examples in FIGS. 1-2 and above-described examples are not meant to imply architectural limitations. For example, data processing system 200 also may be a tablet computer, laptop computer, or telephone device in addition to taking the form of a mobile or wearable device.

With reference to FIG. 3, this figure depicts a block diagram of example caller oriented features for past location-based communication with mobile devices in accordance with an illustrative embodiment. Application 302 is an example of any of client applications 134, 144, or 113 in FIG. 1. Server application 304 is an example of server application 105 in FIG. 1.

Component 312 detects that a caller is initiating a location call. For example, component 312 detects that a map application has been opened, a meeting notice is presented, or a location is input in natural language, on the device where application 302 is executing.

In one embodiment, component 312 also detects that the caller is specifying a past time based condition for a location call. For example, component 312 detects that the caller has provided an input at a certain application and the input has a temporal aspect in the manner described elsewhere in this disclosure.

Component 314 presents an outbound call criteria selection interface. Any parameters of the outbound location call can be specified using the interface presented by component 314. In some cases, component 314 saves a criterion that has been input by the caller on the interface as a preference in configuration 306. In some cases, component 314 presents as a pre-configured criterion, a preference that has been previously saved in configuration 306.

In one embodiment, component 314 presents an interface through which the caller can expressly specify or input a past time based condition as well. For example, instead of component 312 detecting an input with a temporal aspect being made at another application, component 314 presents an interface through which the caller can input the past time based condition to be used with a location call. In one embodiment, the input with temporal aspect, as detected by component 312, can be used to pre-populate the interface presented by component 314. The caller can accept, reject, or modify the input for use as a past time based condition for a location call.

Component 316 transmits the one or more outbound location call criteria (317) to server application 304. Optionally, as described elsewhere in this disclosure, when server application 304 has to evaluate whether a past time based condition has been satisfied, component 316 also sends the past time based condition (317) detected or collected by component 312 and/or 314 to server application 304.

When callee list 319 is available to application 302, component 318 receives callee list 319 from server application 304. In some cases, component 318 may prepare and send a request to server application 304 for callee list 319.

Component 320 enables the caller to select one or more potential callees from callee list 319. In some cases, component 320 automatically selects one or more potential callees, automatically rejects one or more potential callees, or both, based on a preference saved in configuration 306. For example, given a callee list, one embodiment can select a target callee from the callee list based on a degree to which the target callee satisfies the past time based condition, the time at which the target callee satisfies the condition, the location from which the target callee satisfies the condition, or some combination thereof.

As an example, the embodiment may select one callee over another callee from the callee list if a degree to which the first callee satisfies the past time based condition, the time at which the first callee satisfies the condition, the location from which the first callee satisfies the condition, or some combination thereof, is preferable over the degree to which the second callee satisfies the past time based condition, the time at which the second callee satisfies the condition, the location from which the second callee satisfies the condition, or some combination thereof.

As another example, in another embodiment, given a callee list, the embodiment can identify whether anyone on the callee list is also in a contacts list accessible to the caller's device. From this disclosure, those of ordinary skill in the art will realize that configuration 306 may be dynamically computed by application 304 based on information from the Internet such as a social media network.

Component 322 prepares an instruction to initiate the outbound location call. For example, component 32 collects from the caller any messages that are to be delivered to a callee, any limitations on the location call such as a timeout or a number of responding callees, and transmits them as one or more instruction 323 to server application 304.

With reference to FIG. 4, this figure depicts a block diagram of example callee oriented features for past location-based communication with mobile devices in accordance with an illustrative embodiment. Application 402 is an example of any of client applications 134, 144, or 113 in FIG. 1. Application 402 can also be implemented together with the features of application 302 in FIG. 3, in the form of a single application. Server application 404 is an example of server application 304 in FIG. 3.

Component 412 allows a potential callee to configure application 402, the mobile device where application 402 is executing, or both, how the callee would like to handle an inbound location call. A configuration preference provided by the callee is saved in configuration 406. Component 412 may also present to the callee a parameter from configuration 406 as a default configuration or a previously saved preference of the callee. Component 412 may also alter a callee preference based on a time, a location of the callee's device, or a combination thereof, and update configuration 406 accordingly. Optionally, component 412 may send (413) one or more preferences to server application 404.

Component 414 configures the mobile device where application 402 is executing. Particularly, component 414 configures the mobile device to observe or enforce a black zone, DND and other periods, location hiding, location obfuscation or masquerading, and other device configurations described herein.

Server application 404 sends inbound location call 415, or an indication thereof, to application 402. For example, inbound location call 415 may result from instruction 323 sent from application 302 in FIG. 3.

Component 416 detects inbound location call 415. Component 416 accepts, rejects, or allows a failure, of call 415 according to callee preferences in configuration 406. Optionally, when data is requested by a caller or server application 404, as described elsewhere in this disclosure, component 418 sends data 418 to server application 404.

With reference to FIG. 5, this figure depicts a flowchart of an example process for past location-based communication with mobile devices in accordance with an illustrative embodiment. Process 500 can be implemented in application 302 in FIG. 3.

The application detects an initiation of an outbound location call (block 502). The application receives a past time related condition for the outbound location call (block 506). Any number of past time related conditions can be specified in block 504.

The application determines whether one or more of the past time related conditions specifies a location (block 510). If no criterion specifies a past location (“No” path of block 510), the application resolves a criterion into a past location (block 512). For example, if the criterion specifies “when John had a heart-attack”, the application obtains the information of the event and resolves the location of the event from the obtained information in block 512. The application proceeds to block 514 thereafter.

If a criterion specifies a past location (“Yes” path of block 510), the application causes the availability of potential callees at the location to be determined, such as by requesting server application 304 in FIG. 3 to make the determination (block 514). The available potential callees at the location form a set of callees.

Optionally, when the set of callees is available or accessible to the application, the application may select a subset of the callees (block 516). For example, in one embodiment, when several potential callees satisfy a past time based condition, at block 516, the application selects those one or more callees in the subset who satisfy the condition by exceeding a degree of satisfaction.

The application initiates the outbound location call to the set of callees or a selected subset thereof, as the case may be (block 518). For example, when block 516 is not executed, the outbound location call is initiated to the set of callees.

The application determines whether a callee has responded, i.e., accepted the location call (block 520). If no callee has accepted the location call while the location call is still active and pending (“No” path of block 520), the application determines whether a timeout period has elapsed (block 522). The timeout may be a default configuration of the application or a server application. The timeout may also be configured as a criterion in block 504.

If the timeout period has not elapsed (“No” path of block 522), the application returns to block 520. If the timeout period has elapsed (“Yes” path of block 522), the application proceeds to block 530.

If a callee has responded, i.e., accepted the location call (“Yes” path of block 520), the application determines whether a criterion in block 504 or a parameter of the outbound location call configuration prefers a single callee to respond or multiple callees to respond (block 524). If multiple callees are preferred (“Multiple” path of block 524), the application determines whether a threshold number of responses have been received (block 526).

If the threshold number of responses have not yet been received (“No” path of block 526), the application proceeds to block 522 to determine whether the timeout period has elapsed. If the timeout period has elapsed (“Yes” path of block 522), the application sends an instruction to connect the location call with the responding one or more callees (block 530). If only a single callee was expected to respond (“Single” path of block 524), the application performs block 530 as well. If a threshold number of callees have responded (“Yes” path of block 526), the application performs block 530 as well.

An implementation of block 530 may also connect the caller with the one or more callees as the callees respond. For example, such a connection may be progressively established with responding callees as the callees accept the location call in the form of a voice call, a video call, a conference or bridged call, or as text messaging in the form of a group chat.

Optionally, in addition to sending the instruction in block 530, the application may also send a data request as described elsewhere in this disclosure (block 532). The application ends process 500 thereafter.

With reference to FIG. 6, this figure depicts a flowchart of another example process for past location-based communication with mobile devices in accordance with an illustrative embodiment. Process 600 can be implemented in application 402 in FIG. 4.

The application configures a preference for an inbound location call (block 602). The application optionally transmits one or more preferences to a server application, such as to server application 404 in FIG. 4 (block 604).

Many possible preferences can be configured in blocks 602 and 604. For example, one embodiment allows a potential callee to masquerade the location of the potential callee's device as being present everywhere, to wit, anywhere a caller might want to place a location call. The embodiment thus enables the potential callee to accept or reject a location call based on other preferences when the call is actually received.

As an example, masquerading the location such that the location of the callee meets any location criterion of the caller may be restricted to only some callers, such as a list of previous callers, known callers, or callers meeting certain criteria. Such masquerading allows the potential callee to pretend to be present wherever a caller expects some callee to be present. For example, a salesperson could masquerade the location of the salesperson's device to associate the salesperson's device with the locations of multiple sites of a company, such that the salesperson receives a location call regardless of which site a caller intends for a location call. These examples of preferences and configurations are not intended to be limiting. From this disclosure, those of ordinary skill in the art will be able to conceive many other preferences, configurations, and manners of masquerading, and the same are contemplated within the scope of the illustrative embodiments.

The application detects an inbound location call (block 606). The application determines whether the inbound location call meets a combination of the configured inbound preferences (block 608). If the inbound location call meets a combination of the configured inbound preferences (“Yes” path of block 608), the application configures a parameter to be used with the inbound location call (block 610). For example, the application configured the call such that the caller can receive information about the callee, such as the callee's identity, a number or identifier associated with the mobile device where the application is executing, a normalized form of the identity or the identifier, or other similarly purposed information. In some cases, the application may transmit the parameter configured in block 610 to a server application.

The application accepts the inbound location call (block 612). The application ends process 600 thereafter.

If the inbound location call does not meet a combination of the configured inbound preferences (“No” path of block 608), the application determines whether to reject the call or masquerade a device location to avoid the call (block 614).

If the application decides to masquerade a device feature, such as the location of the device (“Masquerade” path of block 614), the application configures and/or transmits a changed parameter of the mobile device (block 616). The application then allows the inbound location call to fail (block 618). The application ends process 600 thereafter.

If the application decides to reject the call (“Reject” path of block 614), the application rejects the inbound location call (block 620). The application ends process 600 thereafter.

Thus, a computer implemented method, system or apparatus, and computer program product are provided in the illustrative embodiments for past location-based communication with mobile devices. Where an embodiment or a portion thereof is described with respect to a type of device, the computer implemented method, system or apparatus, the computer program product, or a portion thereof, are adapted or configured for use with a suitable and comparable manifestation of that type of device.

A network adapter card or network interface in each computing/processing device receives computer readable program instructions from the network and forwards the computer readable program instructions for storage in a computer readable storage medium within the respective computing/processing device.

Computer readable program instructions for carrying out operations of the present invention may be assembler instructions, instruction-set-architecture (ISA) instructions, machine instructions, machine dependent instructions, microcode, firmware instructions, state-setting data, or either source code or object code written in any combination of one or more programming languages, including an object oriented programming language such as Smalltalk, C++ or the like, and conventional procedural programming languages, such as the “C” programming language or similar programming languages. The computer readable program instructions may execute entirely on the user's computer, partly on the user's computer, as a stand-alone software package, partly on the user's computer and partly on a remote computer or entirely on the remote computer or server. In the latter scenario, the remote computer may be connected to the user's computer through any type of network, including a local area network (LAN) or a wide area network (WAN), or the connection may be made to an external computer (for example, through the Internet using an Internet Service Provider).
